Our Philosophy

Our Story

Arctos School is Missy Rohs and a wide, wild community of students and alumni and guest instructors and friends in the Pacific Northwest and beyond.

The seeds of Arctos were planted in 2005 when Missy met Gradey Proctor while volunteering for Bark, an organization dedicated to protecting the Mt. Hood National Forest outside of Portland, Oregon.

Gradey and Missy quickly realized that they shared an intensely nerdy love of plants, with complimentary perspectives: that of an ecologist/botanist and an herbalist/healer. It didn’t take long for them to realize that they both enjoy teaching, too: At that point, Gradey was already moonlighting as a botany instructor, while Missy had been leading radical first aid and civil rights trainings for years.

Some of Our Previous Workshops & Adventures

Edible and Medicinal Plants of the Conifer Forest Plant Walk

On this pay-what-you-can walk, we will wander the conifer woods of Powell Butte with Gradey Proctor to learn plant ID and ecology, as well as the edible and medicinal uses of the plants we encounter. Our hike will be approximately two miles, mostly in a fairly flat section of the park. Bring a curious mind and whatever you need for a leisurely stroll in the forest. Dress for the weather.

The Medicinal Bounty of Your Garden — a free herbalism class

In the Portland area, we are surrounded by a wealth of medicinal plants. Chances are that you’re already growing some in your garden! Missy will talk about some healing herbs that you likely see on a regular basis. We’ll cover when to harvest these plants, how to use them, and more!

Supporting Sleep & Relaxation with Herbs

Anxiety & stress got you wound up? Unable to ground & chill out? You’re not alone! Join Missy to learn about plants that can help you calm down and sleep soundly. We’ll talk about five different medicinal plants in depth, covering best preparations, finding the right dosage, & more. Students will be able to learn by tasting, and everyone will get written materials to take home.

Our 2027 Herbal Immersion offering will start with a six-week foundational section in late March and all of April. We will meet in person every Wednesday and Thursday from 10am-4pm. In this short, intensive course, we’ll build a solid understanding for a well-rounded herbalist: connection with the land that we live on through the lenses of botany and ethical wildcrafting; understanding of medicinal plant actions through organoleptics, phytoconstituents, and herbal energetics; hands-on experience with making tinctures and medicinal-strength preparations; and in-depth exploration of materia medica for digestion and other body systems.

Coming up for 2027, The Herbal Immersion Program will be offered in shorter segments. Full details coming October 20!

Our Instructors

Missy Rohs

Founder and Instructor

Missy Rohs is a community herbalist, a queer nature geek, and a co-founder of The Arctos School. She grows, scavenges, and wildcrafts her own herbs with a focus on sustainable herbal remedies: those that grow easily in populated habitats, and those that can be harvested in the wild with minimal impact or beneficial impact. Her ecological ethos drives a slightly over exuberant love of weeds.
